A rotary adsorbent dryer (22;220) is provided which includes a stationary outer housing (42;242) having spaced stationary end walls (44, 45; 244, 245), and a rotor (54;254) mounted for rotation within the outer housing (42, 242). A plurality of compressed gas passages (46, 47, 48, 49; 237) pass through the end walls (44, 45; 244, 245) to provide compressed gas flow to or from a respective substantially open end of the rotor (54;254). A drive arrangement (D; 103, 303) is provided which is cooperable with an outer circumferential region of the rotor (54;254) so that it is not necessary to provide a drive shaft which extends axially through dessicant material within the rotor (54;254). |
